210 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



posteriorly ; a small irregular oval white apical spot ; a 

 white central streak from base to of disc, at first narrow, 

 rapidly dilated, upper edge straight, lower edge twice 

 toothed obliquely inwards, apex more oblique than hind-margin, 

 indented in middle ; sometimes this streak reappears on hind- 

 margin as a later ally- suffused blotch ; second line visible from 

 extremity of third costal streak to anal angle, slender, blackish, 

 five times very acutely angulated inwards ; in female the whole 

 of the markings are lost except the white costal streaks, the rest of 

 the wing being unicolorous : cilia white, tips and sometimes 

 almost the whole, suffused with dark fuscous, and the dark 

 fuscous parting-line near base, very strongly marked round apex 

 of wing. Hind-wings pale fuscous- grey ; cilia whitish, with 

 faint-grey parting-line. 



Intermediate in general character between the groups of Or. 

 candiellus, Hs. and pratellus, Z., but narrower-winged than any 

 allied European species, and otherwise distinct. Amongst 

 Australian species nearest to concinnellus, Walker, but at once 

 separated by the absence of the dorsal white streak. 



Occurs at South Creek, and in abundance at Parramatta, but 

 local ; comes in plenty to light ; double-brooded, the first brood 

 in October and November, the second in February and March. 



Or. lifractellus, Walker. 



I have come to the conclusion that this species (described in 

 Vol. III., p. 197, as an Eromene] was correctly placed by Walker 

 in Or ambus. Its nearest allies are the group of trivittatus, Z., 

 and especially aurantiacus, which it resembles in form, differing 

 however from all by the broken longitudinal streaks, and metallic 

 fascia. 



Or. impletellus, Walker, Cat. 175. 



^ 11"-13". Head ochreous-brown, with a whitish spot over 

 each eye, and indistinctly whitish behind antennso. Labial
